Full-servo multi-axis injection device for die-casting machine

Abstract

A full-servo multi-axis injection device for a die-casting machine, including a main body, including a hollow frame, servo motor, screw rod, transmission unit, and injection unit, the servo motor being configured on a top of the frame, one end of the servo motor having a deceleration mechanism in connection with one end of the screw rod, another end of the screw rod being in connection with the transmission unit, another end of the transmission unit the injection unit, and the injection unit having at least one input and at least one output. Whereby, the servo motor drives the screw rod to rotate upon running, and the transmission unit converts the rotation of the screw rod to a vertical reciprocating movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(4) Referring to FIGS. 1 and 2, a full-servo multi-axis injection device for a die-casting machine includes a main body 10.

(5) The injection device 10 includes a hollow frame 11, servo motor 12, screw rod 13, transmission unit 14 and injection unit 15, where the servo motor 12 is mounted on the top of the frame 11, and one end of the servo motor 12 having a deceleration mechanism 121 in connection with one end of the screw rod 13, another end of which is in connection with the transmission unit 14, another end of which is coupled to the injection unit 15 having at least one input 151 and at least one output 152.

(6) Referring also to FIG. 3, a first fixing element 122 and second fixing element 131 in connection with each other are respectively configured on one end of the first deceleration mechanism 121 and one end of the screw rod 13, where the first fixing element 122 and second fixing element 131 respectively are a coupling, thereby coupling the first deceleration mechanism 121 to the screw rod 13.

(7) A partition having a through hole (not shown in the figures) is further configured in the frame 11, and the screw rod 13 is passed through the through hole. Furthermore, the screw rod 13 is provided with a third fixing element 132 in connection with the partition 111, and a bearing 1321 in connection with the screw rod 13 is further configured on the third fixing element 132. Furthermore, a position limiting hole 112 is configured on one side of the frame 11, and an engagement portion 141 is projected from one side of the transmission unit 14, where the engagement portion 141 is passed through the position limiting hole 112.

(8) Furthermore, the injection unit 15 is provided with a through hole (not shown in the figures) for the insertion of the screw rod 13 therein, and the input 151 and output 152 are respectively positioned on the bottom face and one side of the injection unit 15, with the two sides of the injection unit 15 being respectively configured slidably on a guide rail 153 and further respectively projected with a combination portion 154.

(9) Thereupon, the servo motor 12 drives the screw rod 13 to rotate upon running, and the transmission unit 14 converts the rotation of the screw rod 13 to a vertical reciprocating movement through the structures mentioned above.
